disk inconsistency - should 'fsck' always executed with -y ?

Do you know of any good references on how to do that, to look for potentially
lost data?

If there's only one disk, and only one partition on the disk (which is how I
typically set up our systems), there wouldn't be any slowdown.  And the
slowdown would only occur when fsck executes.  If the system has been properly
shut down, it almost never executes.

Again, just how does one do that?
